The engine needs to be fed the proper amounts of air, fuel, and spark. The suspension and brakes must be in tip-top shape. The wheels and tires, transmission, cooling system, gauges—even the seats—must all function properly.

Where they run through a hole, the sharp edges are lined with a rubber grommet. Sometimes the loom is divided into sections joined by multi-pin plugs and sockets, so that it can be removed and refitted section by section.

Splices may be used within 30cm of a termination device when attaching to the pigtail spare lead of a potted termination device, to splice multiple wires to a single wire, or to adjust the wire sizes so that they are compatible with the contact crimp barrel sizes.

They have to be connected to the arduino through a motor shield or custom built circuit. They are typically the most expensive. Stepper motors can have 4, 5, 6, or 8 wires. To use them with the arduino, understanding the internal wiring is absolutely necessary. The best way to learn the internal wiring is to assume no manual exists, and "discover" the internal wiring.

The AWG doesn’t have high current requirements, but the board house doesn’t give you a discount for using less copper, so you might as well opt for large (= low-resistance, low-inductance) traces if you have the room.

Use a 25-65 watt iron for most work, and a 150-250 watt one for large cables, or an 8 oz (225 g) gas-heated iron. Working safelyDisconnect both terminals of the battery before doing any work on wiring other than testing. Whenever you work on the car, watch for any part of the loom coming loose from its clips, for there is a risk of it getting trapped or burned. Always replace wiring in its clips.

Brushes are used to create electrical contact to the commutator segments and when current is fed into two of the four brushes, it flows through all the loops of the armature and shoe windings and out the other two brushes. This creates a magnetic field around each loop. As the armature turns, the loop will move to a position where the current flow reverses. This constant reversal of current flow allows the armature and field coils to repel each other and spin the motor. The greater the current flowing in the coils, the greater the magnetic forces, and the greater the power of the motor.

Although this device uses an I2C interface with communication speeds up to 1 MHz, two of the eight pins are dedicated to Alert (pin3) and nReset (pin 6). The Alert pin is intended to be connected, if desired, to an interrupt pin on a microcontroller. According to section 3.5 (ALERT Pin) of the datasheet, "The output of the pin depends on the value of the temperature reading relative to programmable limits," and its function is "explained in a separate application note.
